Título
“Inkjet printing of flexible organic electrodes for tissue engineering
applications”
RESUMO
Inkjet printing has been demonstrated to be able to print all materials required for integrated circuits at low
costs when compared to conventional silicon processing. With the advent of organic electronics, a wide range
of materials became available and the fabrication of devices with unique properties for interfacing with biology
is now possible. One important example is the use of conducting polymer coatings on metal electrodes that are
implanted in the central nervous system, which provides electrical stimulation of neurons. This work reports on
the fabrication of biocompatible organic devices by means of inkjet printing. The devices were fabricated on
Parylene C (PaC), a biocompatible, flexible polymer substrate. The contact tracks were printed using a silver
nanoparticle
ink,
while
the
active
sites
were
inkjet
printed
using
a
poly
(3,4ethylenedioxythiophene)/polystyrene sulfonate (PEDOT:PSS) solution. To insulate the final device, a
polyimide ink was used to print a thick film, leaving small opened windows upon the active sites. Electrical
characterization of the final device and evaluation of its interface with biology (cells culture essays) were
performed. The results show that inexpensive and biocompatible devices can be produced by direct writing
without any pre-patterning or self-alignment techniques using organic inks.
